With on jects of this kind hollow bodies are esp-sci concerned, intended to serve as receptacles for packin and forwarding objects and goods of dii l'erent kinds, 1. i. corn,-.fionr and, chemicals in the shape of powder or pieces, furthermore also as receptacles for sngan loais, violin-cases and other receptacles which must have a determined shape matching the object to be packed, and the like.

0 11 invention particularly relates to proceedings and devices of that kind, whereby the hollow bodies are obtained from thin solutions of paper-fibrin in several coats of paper-fibrin by precipitation of the coats of fibrin upon wire-cloth forms, couching the single coats of paper-fibrin, precipitated upon the wire-cloth forms, in suitable topforms and sucking or squeezing 0d the exceeding liquid. By felting the difierent couched thin layers of the fibrin coats, solid hollow bodies or paper-fibrin provided with bottoms are produced in known manner which bodies, when pressed, dried and, in case of need, provided with a coating preserving them from humidity, may serve the most different purposes. In this operation the formation of the hollow bodies is obtained by the.

shape and formation of the wire-cloth and the top forms which latter may, totally or partly, consist in already known manner, as described in other patents, or" elastic, inflatable material and be provided with convenient trays. According to the desired thickness of Wall of the hollow bodies to be manufac- S estimation of Patent.

ity of diflerent tray l l l'lereas with the moulds were arranged lei rows one iown devices these one or several par the other, these forms no, according to on new invention, ar ged in a row closed itselfir". i. radially in circle one behind other. The corpending mouds are then shifted by a i m ielectromotoric drive each otner or, the radial .arran ernent turned round an axis, in such manner that all wire-cloth forms are simultaneously introduced into the top forms so not at each time a plurality or hollow bodies is advanced a step in their cornpletion and that in each turn of the machine at each feeding movement a ready set of bodies can be taken out of the device. in the-same closed succession of operations the device may produce, according to another embodiment of the invention in addition to the absorption of the exceeding liquid out of the fibrin water, simultaneously the squeezing-oil ofthe water and the drying of, the hollow bodies in special departmentsbr" on particular working tablesTol the device, so that the hollow bodies may finally leave the device in a state ready for use. The final drying of the hollow bodies is in this case eilected by heated moulds which heating may be carried out by steam, gas or the electric current. The manufacture of hollow bodies of paper-fibrin in masses is quickened, facilitated and improved by the new arrangement and the floor-space required for the device is thereby considerably reduced.

By the closed succession of operations, granted by the arrangement according to the present invention, it is possible, after the starting of the work, to withdraw in each single couching operation a plurality of hollow bodies from the machine, corresponding to the number of moulds arranged in every section of the plant, because as many couchings will successively take place on the machine as the ready hollow bodies are to I instance, it is thereby possible to produce in present invention. In it only those parts.

present layers of fibrin. In all working sections of the couching departments of the machine new series of hollow bodies are incessantly brou ht nearer to complet on. By usingfor the iiferent layers of iibrlnin the hollow bodies diiferently composed, more or less diluted or also 'difierentl stained fibrinwater, the kind and the t ickness of the layers of fibrin to be couched in succession and with it, the nature and the thickness of wall of the ready'hollow bodies may be varied in a determined, desired manner. For

masses hollow bodies having as much as possible uniform total thickness of wall, the equalization being attained by one or several thicker or thinner, layers of fibrin made of fibrin-water of a corresponding density.

The drawing shows in a schematlc manner the working of an embodiment of the have been drawn which are indispensable for the understanding of the device. Mechanical and constructive details haye'not been drawn. Consequently the drawingrefers only to an embodiment WhlQh may be altered and constructively, modified'in many a way.

Fi 1 shows schematically in a longitudina cut a device for manufacturing comcal hollow bodies; I

Fi 2 shows in a top-view amodel of the WOIklIl departments of the device for manufacturmg, hollow bodies.

In the shown embodiment of the invention always 6 sets of ,3 wire-cloth and top forms each are workin together.

In the annular fibr n-water-receptacle a the wire-cloth forms z co-operating with the top-forms k, .are provided for upon plates ti, adapted to be hydraulically lifted. In this arrangement the top forms 70 are secured to a rotating disk 6, journaled upon a column c. The wire-cloth forms are moved by the cylinders f of the hydraulic presses, provided with the pipings h for sucking in the air and the delivery pipings g and at the same time the fibrin-water is sucked through the wirecloth forms 21, for the purpose of forming layers of fibrin upon the wire-cloth forms. For manufacturing hollow bodies of a determined thickness of wall, the wire-cloth forms and the corresponding top forms have different inner and outer diameters which in the progress of'the work are varied for about the thickness of the layer of fibrin couched into the preceding top forms. For this purpose top forms are conveniently provided with interchangeable trays secured to them. These trays are expelled, either automatically or by hand, out of the top forms arriving in turn above the table 1 and containing the objects of the desired thickness of fibrin. In the movement of the rotating part of the device new trays are inserted at the and interchangeable above the table Z.

this pur ose the top forms may be connected, if. i. to t e plate b, by guides, by a bayonettable at into the emptied top 'forms'and the work is going on as before. The expulsion of the trays outoi thetop forms may if. i..be done in knownner'by releasing the mechanically barred "trays by the striking against a lever in front of or at the table 6 and are automatically expelled out of the set of top forms arriving above the table. But in case of need the trays may electro-magnetically be retained-in the top forms and released by demagnetization or reversal of magnetism." 4 v The top-forms and their trays may in known manner he made of two or more parts. The top forms may, instead of being provided with trays, be of difierent desi s or clutch or in similar manner.

Whereas with the shown embodiment'of our invention the squeezing-0E of the surplus water and the complete drying of the hollow bodies has to be operated outside the shown device, bodies consisting of few layers of fibrin may, in'the first line, be pressed dry in special departments of the device and made ready thereupon. With such a device two or three sets of wire-cloth forms would be existing for the couchingprocess proper in the manufacture of 2 or 3 layers of fibrin, when other departments, f. i. 2 or 3 of them, would serve for squeezing ofi' the water by means of the wire cloth forms which are introduced into the top forms and to these squeezing tables are connected other drying tables, upon which the already ressed hollow bodies are completely drie by the insertion of suitably heated under-forms into the top forms, so that the ready hollow bodies will arrive u on the delivery-table, connected to thedrymg tables.

The top forms may also be moved against the bottom forms, although the reverse arrangement will prove more fitted for the purpose.

It is neither absolutely necessary that the forms be arranged radially round a rotating axle. The tables might also be rouped elliptically instead of in a circle, w ereby a conveniently arranged feeding movement ought to be provided for. of the operation can also be attained by the arrangement of movable forms fastened to an endless chain with a simultaneous convenient arrangement of the corresponding wire-cloth forms and the like according to the principles of the present invention.
